rMPRovnn BEER-coonn'n *Mw- The Schedule referred to in these LettersYPatent and making part of the same.`

To all whom 'it may concern i y y Be it known that we, JorN YATEs andEDGAR l 'DEUELL, ofthe city of Brooklyn, in the countyof' Kings, andState of New York, have invented a new and improved Apparatus or Devicefor. Cooling Beer .and other liquids; and that the followingdescription,

s our invention may be distinguished from all others of f asimilarclass, together with such parts as we claim, and desire to have securedto us by Letters Patent.

This invention relates to a new and improved apparatus or devicefor'cooling beer and other liquids.v The invention refers to animprovement in that class of coolers in which cold water is made to passthrough a series of"l pipes, and the warm liquid to be cooled .made topass over said pipes.

The invention consists in an improved means by which the ends of thepipes are connected or made to communicate one with' another; and, also,to a means for enclosing the series of pipes by which the beer or otherliquid1 in passing down over the cool-water pipes, is protected from theexternal air; p e

The object of thev invention is to obviate the difficulties which nowpresent themselves in the cooling of beer and other liquids, by thesemeans:

First, the leaking of the connections or joints of the pipes, a resultdue to the expansion and contraction j of the pipes under the extremesof temperature to whi'ch .thejnare subjected; and,

Second, the deterioiation of the liquid while being Y cooled, especiallybeer, by exposure to the atmosphere'.

In the accompanying sheet of' drawings- Figure 1 represents a verticaicentral section of our invention, taken in the line :v x, fig. 2.

Figure 2, a plan or top view of the same.

` A Similar lettels of reference indicate corresponding parts in theseveral drawings. p

A represents a series of pipes or tubes,which are -placed one above theother, and have their ends fitted in plates, B B, and secured therein byset-screws or othermeans, which will admit of the pipes or tubes beingreadily detached, when necessary.

The 'pipes or tubes A project through the plates B B, and extend intoboxes, C C, which are secured by screws, or othelwvise, to theoutersides of the plates all danger of breakage, by means of th'e expansionand contractionof metal, avoided; and, in case the pipes or tubesrequire cleaning, the boxes C ma)r be detached, and also the pipes ortubes, and the latter thoroughly cleansed, and replaced without anytrouble or difculty whatever.

`The beer, or` other liquid to be cooled, isallowed to descend into'atrough, D, placed directly over the uppermost pipe or tube A, said'trough having a perforated bottom, through which the warm beer or otherliquid is allowed to pass, and descend over the pipes or tubes A,thehlatter having a current of cold water passing through them, from thebottom one upward, 'as indicated by the arrows. The beer or other warmliquid,in passing down over these cool-water pipes, is cooled, the beeror other liquid dropping into a receiver, E, underneath the lowest -pipeor tube A, from which it is discharged, through a pipe, F, into a propervat or receptacle designed to receive it.

In the cooling of many liquids, especially beer, it is essential thatprovision be made against exposure to `the external air, and to this endwe enclose the pipes lortubes, A by doors, E E', one end of which ishinged to one of the boxes .0. These doors, when closed, admitotheliquid to bo cooled passing down over the exterior sunface of the pipeor tubes A without being exposed to the external air, and, at the sametime, do not in the least prevent tree access to the pipes or tubeswhenever required. l

The ordinary coolers, of the class herein described, have the ends oftheir water-pipes connected by elbows or V-joints, and theseare verydiflicnlt to keep watertight, owing to the expansion and contraction ofthe pipes under the variable temperature to which they are supjectcd,the warm beer in the one case passing down over'the exterior surfaces ofthel pipes or tubes, and the cold water in the other case passing upthrough the-pipes cfr tubes A. Our improvement e'ect-nally obyiates thisdiliioulty, as' the pipes or stubes may ex, pand and contract, and theirends, at the same time,

tit tightly in the boxes C G, and, as the pipes or tubes v are renderedvery accessible, theylnaybe cleansed when'- ever required, without anytrouble or difficulty whatever. 1 Y

`"Ve do not claim, broadly, the cooling of beer and other liquids, byallowing the same to pass through. a i

perforated trough over a series of -pipes or tubes, through which acurrent of cold water is made to flow,

for this isan old amlwell-knowu device, and in general use, especially-in breweries; but

We do claim as new, and desire to secure by Letters Patent- 1.Connecting the ends of the pipes or tubes A by f means of boxes, C,divided into compartments Vby means of partitions a., the ends of thepipe's or tubes passing throughY suitable standards or plates, B, intothe compartmentsof said boxes, substantially as shown and described..

2. Enclosing the series of pipes or tubes A by means
